Professor Isabelle De Groote, from Ghent University in Belgium, led a project studying the remains of a prehistoric woman who lived in what is now Belgium around 10,500 years ago.
Using ancient DNA, the team reconstructed her face and discovered that the woman differed from most other remains analysed from the same period and place.
In fact, the researchers believe the woman came from the same population group as the Cheddar Man, who lived in what is now the UK at around the same time, but had lighter skin.
